Irby Construction Company
(opens in a new tab)Irby Construction Company, A Wholly Owned Subsidiary of Quanta Services, Inc., excels in the processes required for major transmission, substation and distribution line construction and has demonstrated that ability with successful projects.
In construction, we look out for our own and each other’s physical safety every day. We should do the same when it comes to mental health.
We’re committed to making mental health and suicide prevention an ongoing part of our safety culture, not a conversation that gets tucked away until there’s a crisis. At Irby Construction, that means carrying this conversation forward beyond Construction Suicide Prevention Week and continuing to look out for one another, both on and off the jobsite.
For Irby employees and their families, resources and support are available through the Employee Assistance Program (EAP). Access those resources here: MagellanAscend.com
If you or someone you know is struggling, don’t wait to reach out. Call or text 988 to connect with the 988 Suicide & Crisis Lifeline.
Team Irby: Look out for your crew. Ask the question. Start the conversation. You never know when a simple check-in could make a difference.

Construction Suicide Prevention Week sheds light on an undeniably important and difficult issue facing our industry. But the conversation around mental health and suicide cannot stop when the workday ends or the weekend begins. This is an issue that affects our people every day, both on and off the jobsite.
That’s why it’s important to know what resources are available when someone needs support. One of those resources is the 988 Suicide & Crisis Lifeline.
Available 24/7, 988 provides free, confidential and judgment-free support to anyone experiencing a mental health or suicide-related crisis. You can call, text or chat with a trained counselor and connect with someone who can help.
